Titanium VT1-0-ANN vs VT1-0-CW
Titanium · VT1-0 temper comparison
VT1-0-ANN and VT1-0-CW are two conditions of the same titanium grade, VT1-0: ANN (annealed) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. VT1-0-CW is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 320 MPa (46.4 ksi) for VT1-0-ANN, about 63% more; tensile strength follows at 600 MPa (87 ksi) vs 450 MPa (65.3 ksi). In exchange, VT1-0-ANN is the more ductile: elongation 28% versus 10% for VT1-0-CW, and VT1-0-CW is harder (210 HB vs 155 HB). VT1-0-ANN runs hotter in service (300°C vs 250°C continuous).
VT1-0-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
VT1-0-CWChoose it when strength drives the design.
VT1-0-ANN vs VT1-0-CW: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

VT1-0-ANN vs VT1-0-CW — frequently asked
Is VT1-0-CW stronger than VT1-0-ANN?
Yes. VT1-0-CW has a typical yield strength of 520 MPa (75.4 ksi) against 320 MPa (46.4 ksi) for VT1-0-ANN — about 63% more. Tensile strength is 600 MPa (87 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, ANN or CW?
ANN is the default VT1-0 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose VT1-0-ANN over VT1-0-CW?
Pick VT1-0-ANN when the part is bent, formed or impact-loaded, or when the part sees heat. Pick VT1-0-CW when strength drives the design.
